| The '''SUNPLUS SPLB32A''', an 8-bit CMOS microprocessor, contains 1216 bytes working RAM, 512K bytes ROM, 8 I/Os, interrupt/wakeup controller, UART for serial communication and Serial SRAM interface for memory expansion, and automatic display controller/driver for LCD. It also features one PWM/DAC driver with two audio channels to produce attractive sound effects easily. Its large ROM area can be used to store both program and audio data. The built-in UART speeds up data transmission between two devices. Furthermore, a SLEEP (power-down) function is also built in to extend power life. The SPLB32A is designed with SUNPLUS state-of-the-art technology to fulfill LCD application needs, especially for hand-held products.
